Abstract
The utility model relates to a manual hydraulic lifting apparatus which belongs to a field of mechanical technology. The utility model is formed by the improvement of an original hydraulic lifting apparatus; a demountable gag lever post with a steel ball is arranged on the lateral face of a base arranged under a small oil pump, and the body of the demountable gag lever post with a steel ball penetrates into the base and is crossed with the oil inlet hole of the small oil pump. An oil-proof plug is arranged on the bottom of a base arranged under a working oil cylinder 2, an annular oil groove and a cross oil hole are arranged on the oil-proof plug, and the oil-proof plug is communicated with an oil filling valve arranged on the top of the oil-proof plug. The utility model has the advantages of reasonable structure and convenient repair and maintenance; besides, the service life of the utility model can be extended.
Description
The utility model relates to the hand-hydraulic jack up unit that loading-unloading vehicle etc. uses, and belongs to the hydraulic machinery technical field.
Existing hand-hydraulic jack up unit, hand-hydraulic jack up unit as the loading-unloading vehicle adapted, constitute by handle, little oil pump, operating cylinder, base etc., the in line check valve of little oil pump and operating cylinder all is provided in a side of on the base, between check valve and little oil pump, operating cylinder spring leaf is set, steel ball is run in the piston cylinder when preventing the piston cylinder oil-feed.Bar handle, during the piston upward movement of little oil pump, the one-way valve opens of little oil pump bottom, fluid through oil duct in the oil storage barrel in the drawing pump oil cylinder, when moving downward under the effect of pump piston at bar handle, the closed check valve of little oil pump bottom, pressure oil is through another oil duct and make the one-way valve opens of operating cylinder bottom, pressure oil enters in the operating cylinder, and promotes piston, piston rod upward movement.Little oil pump and operating cylinder and base all are welded; oil duct and check valve be because long-term use, the obstruction of dirt or malfunctioning occurs through regular meeting, and maintenance is difficulty relatively; need to push reed earlier open with an elongate rod; could take out the steel ball in the check valve, because the interior aperture of oil cylinder is little and dark, and the aperture of oil duct is littler and length; bring cooresponding inconvenience to maintenance; even can not repair, change a complete set of hydraulic hoist unit again, cause very big waste and influence the work of complete machine. at all
The purpose of this utility model is exactly the deficiency at above-mentioned hand-hydraulic jack up unit, and a kind of novel structure is provided, and simple, maintenance is the hand-hydraulic jack up unit easily.
The purpose of this utility model is achieved in that the hand-hydraulic jack up unit is to improve to form on the basis of existing jack up unit, it comprises little oil pump 1, operating cylinder 2, oil storage barrel 3, handle 4, base 5, inlet valve 6, inlet valve 7, it is characterized in that jack up unit is provided with steel ball position-limited lever 8 and anti-plug cock 9; Steel ball position-limited lever 8 is located at the side of the base 5 below the little oil pump 1, and shaft penetrates base and intersects with the fuel feed hole of the little oil pump on inlet valve 6 tops; Anti-plug cock 9 be located at base 5 below the operating cylinder 2 below, anti-plug cock 9 is provided with oil groove and oilhole and communicates with the inlet valve 7 at top, base 5 is provided with the fuel feed hole 13 that inlet valve 7 communicates with operating cylinder 2.In order to guarantee between anti-plug cock 9 and the base 5 good sealing property is arranged, anti-plug cock 9 is provided with seal ring (10,11,12) with base 5 contacted tops, side and end shoulder place.The fuel feed hole 13 that the inlet valve 7 that is provided with on the said base 5 communicates with operating cylinder 2, preferably the oilhole group of forming by 3～4 little oilholes.When inlet valve 6 need be maintained because of situations such as greasy dirts, only need dismounting steel ball position-limited lever 8 down, can from the piston cylinder of little oil pump, take out the steel ball in the inlet valve 6 easily after, clean and keep in repair.In the time of need keeping in repair as inlet valve 7 et out of orders, only need below base 5, to dismantle anti-plug cock 9 down, can keep in repair easily.
The utility model is simple and reasonable, and is easy to manufacture, and cost is low, is convenient to maintenance, increases work efficiency, and increases the service life.
Accompanying drawing 1 is a structural representation of the present utility model, 1 little oil pump, 2 operating cylinders, 3 oil storage barrels, 4 handles, 5 bases, 9 anti-plug cocks among the figure.
Accompanying drawing 2 is the structural representation of base portion of the present utility model, 1 little oil pump, 2 operating cylinders, 3 oil storage barrels, 5 bases, 6 inlet valves, 7 inlet valves, 8 steel ball position-limited levers, 9 anti-plug cocks, 10,11,12 seal rings, 13 fuel feed holes among the figure.
Accompanying drawing 3 is the structural representation at steel ball position-limited lever of the present utility model position, 1 little oil pump, 5 bases, 6 inlet valves among the figure.
Narrate case study on implementation of the present utility model below in conjunction with accompanying drawing.
The steel ball position-limited lever hole of on the side of little oil pump 1 lower base 5, drilling, and the bar hole is placed between little oil pump 1 and the inlet valve 6, bar hole and fuel feed hole intersect, and steel ball position-limited lever 8 stretches in the bar hole, blocks the steel ball in the inlet valve 6, prevents that steel ball from running in the little oil pump.Steel ball position-limited lever 8 adopts with the aperture in bar hole and is threaded, and is provided with seal ring, prevents leakage of oil.Also steel ball position-limited lever 8 can be arranged in the high pressure output oil duct of little oil pump.Drill below the base 5 below operating cylinder 2 and prevent the hole, installation site of plug cock 9, the top of base 5 do not got through, and leaves capping, makes a call to 4 little oilholes composition oilhole groups and communicate with operating cylinder 2 in capping.Establish annular oil groove and cross oilhole on the anti-plug cock 9 and communicate with the inlet valve 7 at top, annular oil groove communicates with fuel feed hole in the base.In addition on anti-plug cock surrounding wall and shoulder place, the end establish seal groove, anti-plug cock 9 end faces and circle Gu Bi are upward, establish seal ring 10,11,12 in the seal groove at end shoulder place.Adopt bolt will prevent that plug cock 9 is fastened on the base 5.Also can directly adopt between anti-plug cock 7 and the base 5 be threaded fixing.
